It is well known that sediment, burned-out rna terial and condensation water contained in crude oil does not permit proper combustion and entail intermittent flame, lowering of pressure, imperfect flue connection, vibration of the sheets and generally unsatisfactory conditions in the fire |box. Sediment and sludge in the feed tubes do not allow the proper circulation of oil and interfere with the proper functioning of the atomizing burner of the boiler and produces carbon scale on the burner tip which thus impairs efficiency -in producing heat and also requires frequent and costly repairs.

It is further necessary to maintain a uniform temperature for the oil so that it may have the proper viscosity for proper combustion as well as for properly feeding the oil to the burner, and it is accordingly an object of the present invention to overcome such unsatisfactory and objectionable conditions by regulating the temperature and parts throughout, and in which:

lindrical members 5 and 6 supported in a hori-V zontal position one above the other by connecting plates i at the ends of the members.

The ends of the cylinder 5 are closed by end plates 8 and 9, while the ends of the cylinder` f5 are closed by end piates IEB and II.

A transverse partition I2 is provided in the cylinder separating the same into compartments I and Id. A 1` A valve l5 provides a connection between the compartment I3 of the upper cylinder 5 and the lower cylinder 5 while a similar valve lil provides connection between the compartment id and the lower cylinder.` A haiile i? is provided in the upper portion of the cylinder 3 between the valves I5 and lili A crude oil intake pipe I8 is attached to the end plate S of the upper cylinder 5 leading from a suitable source of supply or storage tank and a discharge pipe IS communicates with the compartment i3 by way of the opposite end plate 8. A temperature indicator or thermometer 20 is'attached to the discharge pipe i9.

The side of the partition I2 in the chamber I3 is formed with a lug 2l received in a recess 22 in one end of a cylindrical strainer 25, the other end of the strainer communicating with the discharge pipe i9, as shown to advantage in Figure 3 of the drawings.

A steam heating coil 2d is supported in the lower portion of the lower cylinder 5 by means of brackets 25, the coil being connected to a steam supply pipe 26 on the outside of the cylinder leading from a steam boiler (not shown) for supplying steam under pressure to the coil.

A branch pipe 2l is also connected to the pipe 26 and communicates with the chamber I3 through a tubular nipple 52 which extends through one side of the upper cylinder 5. A conventional form of manuallyoperated valve`23 is provided in the pipe 21. i

The end of the coil 2t remote from the steam pipe 26 is provided with a pet cock 29 to drain water condensed in the coil 24. A steam valve 50 in the pipe 25 .regulates the iiow of steam to the coil 24. Y

A branch pipe 30 is also connected to the steam pipe 26 leading into the side of the lower cylinder 6 and provided with a valve 3| for the admission of steam for flushingv out thecylinder ,6A and the lower portion of the cylinder 6 is provided with a drain 32 having a valve 33 therein.

A branch pipe 34 is also connected to the'pipe 21 and communicates with the chamber I4 an idiain 'valve`33'j ,servel'tol at leastpartially clean th iilte'r or ,s'trainer23'f Ifi-tfisdesired-to blow out theiiuelV through the side of the cylinder 5, and is like- Vwise provided with a control valve 35.

A by-pass pipe 36 connects the chambers I3 and I4 and is also provided with a control valve Y 31.

To the end plate l of the lower cylinder 6 is attachedfa'1water-1gauge 38 toiudicaterthe level of liquidi'n the 'cylinder'f theI upper and lower ends of the gauge being connected toV the cylinder` by Vmeans ofV tubes V5I having screens V39' formed on the ends thereof.

Y In the operation of the device, crude oilfrom the supplyY tank enters thefchamber-I4-byfway.Y

ofthe intake pipe i8 and passes'downwardly throughthe valve I6 into the lower cylinder 6.

The oilY then passes under the baiile II and vis heated by the steam coil 24 and then passes'upwardly into the chamber I3 by way of the valve' I5. Thereafter, the oil passes through the strainer 23 and outof the chanber I3 to the oil burner, not;-sh'own,f;by-way of the supplypipev I9. At this-time;,-the steam Vvalveil is opened to supply steam to the fheatingfcoil Z4, but the bypass control valve 3 `andthe'remaining,steam valves 3l, 2Icfad3'r'arecl'osed,-as' is the pet cock 2S and Y Y drain'valve 33.'
